Fermi Surface Nesting and Nanoscale Fluctuating Charge/Orbital Ordering in Colossal Magnetoresistive Oxides

We used high resolution angle-resolved photoemission spectroscopy to reveal the Fermi surface and key transport parameters of the metallic state of the layered Colossal Magnetoresistive (CMR) oxide La1.2Sr1.8Mn2O7. With these parameters the calculated in-plane conductivity is nearly one order of magnitude larger than the measured DC conductivity. This discrepancy can be accounted for by including the pseudogap which removes at least 90% of the spectral weight at the Fermi energy. Key to the pseudogap and many other properties are the parallel straight Fermi surface sections which are highly susceptible to nesting instabilities. These nesting instabilities produce nanoscale fluctuating charge/orbital modulations which cooperate with Jahn-Teller distortions and compete with the electron itinerancy favored by double exchange

Disruptive Innovation: How Washington State University Is Reaching Urban Audiences

Washington State University (WSU) is redefining how Extension works in urban areas. Its Metropolitan Center for Applied Research and Extension (Metro Center) engages nontraditional Extension audiences using an innovative business model that focuses on short-term projects instead of long-term programs. Outcome-driven, client-centered, and solution-oriented, the Metro Center works to develop practical, place-based solutions by being a conduit between metropolitan decision makers and WSU faculty expertise across the state. In this article, we present a case study centered on the conditions and opportunities leading to the Metro Center\u27s formation, the center\u27s entrepreneurial business model, and center projects that allow Extension to reach new audiences

Business models for reducing greenhouse gas emissions from food loss and waste: Crates to transport tomatoes in Nigeria could reduce food loss and emissions by 36%.

Losses occur in transportation because tomatoes are placed in large woven baskets, and then stacked on top of one another for the journey to Lagos. Plastic crates can be stacked on top of one another without damaging the tomatoes at the bottom of stacks. Crates would also improve ventilation during transport. Losses can be reduced from 41% to 5% through use of crates. Furthermore, baskets are used on a one-time basis and must be replaced after each journey, and the crates are reusable

Expérimentation et validation de situations d'apprentissage, élaborées par le groupe de recherche Archimedes, qui visent à développer la pensée créatrice d'élèves du primaire

L'objectif de cette expérimentation est de développer la pensée créatrice d'élèves du premier cycle du primaire au Québec et d'en vérifier l'impact à partir de l'expérimentation de vingt situations d'apprentissage en éducation physique, élaborées par le groupe de recherche grec Archimedes. Cette recherche-action qui implique 12 élèves du premier cycle du primaire, comprend les étapes suivantes : a) des entrevues initiales auprès des titulaires, b) une première passation du test TCAM, c) l'expérimentation des situations d'apprentissage, d) une seconde passation du test TCAM et e) des entrevues finales auprès de la titulaire. Les données ont été recueillies à l'aide d'observation, de photos, de vidéos et des résultats des tests TCAM. L'analyse des résultats démontrent que les participants acquièrent de la confiance et développent leur pensée créatrice tant au niveau de la fluidité des idées qu'au regard de la qualité de ces dernières

Business models for reducing greenhouse gas emissions from food loss and waste: Reducing milk spoilage in Kenya could reduce food loss and emissions by 10.5%.

Satellite coolers and farmer training programs reduce the amount of time milk is exposed to high temperatures and unhygienic conditions. Coolers can potentially reduce losses during storage by 6%, while extension programs that introduce proper handling practices can reduce losses by 4.5%. Although these measures require significant investment, they pay for themselves so expenses can be shared among groups of farmers at the cooperative level

Business models for reducing greenhouse gas emissions from food loss and waste: Improving cereal storage in Tanzania could reduce food loss and emissions by 14%

Farmer investment in hermetically sealed cereal storage bags can greatly reduce farmer losses. The bags protect cereals and other crops from insect infestation and other potential damages, reducing post-harvest loss from an average of 14% to less than 1%. Additionally, the bags enable farmers to store cereals, protecting them from volatile market prices and especially the low prices that occur immediately after harvest and allowing them to sell months later, when prices are higher
